Lemures often have appearances of things that would appear in a circus, like clowns, jugglers, or even balloons and balls. As the show progresses, the Lemures get more and more goofy, as pointed out by Sailor Moon and Sailor Chibi Moon during the fight Ponko. The ones who resemble balloons seem to be related to each other.

The Lemures sent by the Amazoness Quartet usually have repeated words in their names (like Garagara and Kerokero), and eat the dream mirrors once they are extracted, usually through an extra mouth on their chest. The mirror would be released unharmed whenever Sailor Moon destroyed them.

When they are destroyed, the Amazon Trio's Lemures cracked into pieces and disappeared, while Amazoness Quartet's Lemures shattered into pieces violently.

It is ultimately revealed that they are the "living ghosts" of the people of Queen Nehelenia, whose dream mirrors were taken by her. They were given to her seemingly willing, but it is unlikely they knew the cost allowing this.
